<ul>
<li>Designed for serious microcontroller applications, the Stellaris family
provides the entry into the industry's strongest ecosystem, with code
compatibility ranging from $1 to 1 GHz.</li><br>
<ul>
<li>Superior integration saves up to $3.28 in system cost</li>
<li>Over 130 Stellaris family members to choose from</li>
<li>Real MCU GPIOs&#8212;all can generate interrupts, are 5V-tolerant, and have
programmable drive strength and slew rate control</li>

<li>Advanced communication capabilities, including 10/100 Ethernet MAC / PHY,
USB and USB OTG and CAN controllers</li>
<li>Sophisticated motion control support in hardware and software</li>
<li>Both analog comparators and ADC functionality provide on-chip system
options to balance hardware and software performance</li>
<li>Development is easy with the royalty-free Stellaris Peripheral Driver
Library's high-level API interface to the entire Stellaris peripheral set</li>
</ul><br>
<li>Stellaris microcontrollers feature the ARM<small><sup>&reg;</sup></small> Cortex<small><sup>&trade;</sup></small>-M3
microcontroller core:</li><br>
<ul>
<li>Optimized for single-cycle flash usage</li>
<li>Deterministic, fast interrupt processing: always 12 cycles, or just 6
cycles with tail-chaining</li>
<li>Three sleep modes with clock gating for low power</li>
<li>Single-cycle multiply instruction and hardware divide</li>
<li>Atomic operations</li>
<li>ARM Thumb2 mixed 16-/32-bit instruction set</li>
<li>1.25 DMIPS/MHz&#8212;better than ARM7 and ARM9</li>
<li>Extra debug support including data watchpoints and flash patching</li>
</ul><br>
<li>Stellaris microcontrollers offer capabilities beyond ARM7 for the
microcontroller market:</li><br>
<ul>
<li>Requires approximately half the flash (code space) of ARM7
applications</li>
<li>2&#8211;4 times faster on MCU control applications</li>
<li>No assembly code required - ever!</li>
